Abstract
Lymphoma is a general term for a group of cancers that originate in the lymphatic system and it is the most common hematopoietic malignancy. Overall incidence of lymphoma is increasing globally, with age-adjusted incidence rates for NHL being highest in more developed countries. The incidence is also rising in sub-Saharan Africa where the prevalence of HIV is the highest in this part of the world (1). The lymphomas are divided into two major categories: Hodgkin lymphoma (HL) and non-Hodgkin lymphoma(NHL). Appropriate management of lymphoma begins with an accurate and precise diagnosis. Traditionally, this has necessitated a surgical (either excisional or incisional) biopsy specimen to obtain adequate tissue. Lymphomas have been historically staged by Ann Arbor staging system introduced in 1970. This system, however, was modified in 1989 because of the introduction of CT (Costwald staging classification). Cross-sectional imaging (CT scan, MR imaging, US) is primarily used to detect lymph adenopathy and the pattern of nodal involvement. However, anatomic imagings are limited in accurate lymphoma evaluation as small lymph nodes may harbor malignant cells, whereas large lymph nodes may be benign. Functional imaging, such as positron emission tomography (PET) with fluorodeoxyglucose (FDG), has shown promising results in the diagnosis of lymphoma and complete assessment of the extent of disease. It is also very useful in the follow-up of PET-avid lymphoma (13, 39). This study reviewed articles on imaging patterns of abdominal lymphoma and using qualitative and quantitative data collecting techniques we give the practicing physicians a good knowledge on ultrasound patterns of abdominal lymphoma. And our study results showed lymph nodes in the abdomen and other sites are most common to be involved by lymphoma. According to the result liver involvement outnumbers from other abdominal organs. And pathology result showed NHL type is most common in our study .
